Instagram is embracing its true identity as a mail-order catalog. The question will be how much power merchants will give Instagram after seeing what its parent Facebook did to news outlets that relied on it. In a move that could pit it against Pinterest and Wish, Instagram is launching Shopping features across its app to let people discover and consider possible purchases before clicking through to check out on the merchant’s website.

Today, Instagram Explore is getting a personalized Shopping channel of items it thinks you’ll want most. And it’s expanding its Shopping tags for Instagram Stories to all viewers worldwide after a limited test in June, and it’s allowing brands in 46 countries to add the shopping bag icon to Stories that users can click through to buy what they saw.

Instagram clearly wants to graduate from where people get ideas for things to purchase to being a measurable gateway to their spending. 90 million people already tap its Shopping tags each month, it announced today. The new features could soak up more user attention and lead them to see more ads. But perhaps more importantly, demonstrating that Instagram can boost retail business’ sales for free through Stories and Explore could whet their appetite to buy Instagram ads to amplify their reach and juice the conversion channel. With 25 million businesses on Instagram but only 2 million advertisers, the app has room to massively increase its revenue.

For now Instagram is maintaining its “no comment” regarding whether it’s working on a standalone Instagram Shopping app as per a report from The Verge last month. Instagram first launched its Shopping tags for feeds in 2016. It still points users out to merchant sites for the final payment step, though, in part because retailers want to control their relationships with customers. But long-term, allowing businesses to opt in to offering in-Instagram checkout could shorten the funnel and get more users actually buying.

Shopping joins the For You, Art, Beauty, Sports, Fashion and other topic channels that launched in Explore in June. The Explore algorithm will show you shopping-tagged posts from businesses you follow and ones you might like based on who you follow and what shopping content engages you. This marks the first time you can view a dedicated shopping space inside of Instagram, and it could become a bottomless well of browsing for those in need of some retail therapy.

With Shopping Stickers, brands can choose to add one per story and customize the color to match their photo or video. A tap opens the product details page, and another sends them to the merchant’s site. Businesses will be able to see the number of taps on their Shopping sticker, and how many people tapped through to their website. Partnerships with Shopify (500,000+ merchants) and BigCommerce (60,000+ merchants) will make it easy for retailers of all sizes to use Instagram’s Shopping Stickers.

What about bringing Shopping to IGTV? A company spokesperson tells me, “IGTV and live video present interesting opportunities for brands to connect more closely with their customers, but we have no plans to bring shopping tools to those surfaces right now.”

For now, the new shopping features feel like a gift to merchants hoping to boost sales. But so did the surge of referral traffic Facebook sent to news publishers a few years ago. Those outlets soon grew dependent on Facebook, changed their news room staffing and content strategies to chase this traffic, and now find themselves in dire straights after Facebook cut off the traffic fire hose as it refocuses on friends and family content.

Retail merchants shouldn’t take the same bait. Instagram Shopping might be a nice bonus, but just how much it prioritizes the feature and spotlights the Explore channel are entirely under its control. Merchants should still work to develop an unmediated relationship directly with their customers, encouraging them to bookmark their sites or sign up for newsletters. Instagram’s favor could disappear with a change to its algorithm, and retailers must always be ready to stand on their own two feet.
